opening a port has to be done by experts.. hmm.. if you are in america, call your ISP and demand for a tier 2 or the techsupport supervisor and have your CPE or the modem/router port be opened.
Some routers are at 192.168.1.1 instead of 192.168.2.1, just in case that doesn't work. You'll need to know the password, which if not set will have a default factory setting which is different for various brands. After that, you'll need to use port-forwarding. Sometimes they don't use that specific wording, but a little context searching through the menus and you'll figure it out. From there you just type in the network IP address you want to open the port to and type in the port number you want to open.
Depending on your version of Windows Vista, you may also need to change your firewall rules to allow outgoing connections.
There are some possibilities for this issue, we need some more info:
- Do you have a firewall installed, or do you use the built-in vista firewall?
- Is your PC behind a router and what kind of router is it (brand name or something like that)
- Do you share your connection with other computers?
- Try to give us some information on your ip adress, it will help us determine the kind of network you are on. You can get this information by going to the start menu, then click run. Type "cmd" and press enter. You now get a black window reminding of old DOS times. Now type "ipconfig /all" and press enter again. You now get a lot of probably confusing information on your network. It would really help us if you copy this information and post it here.
If you provice some of this info i will try to help you solve your problem.
Do you want to open tho port for outgoing connection or for incoming connection? Do you already have some software, which will use this port?
Basically, client side TCP port was opened automatically. Just as when you have opened some browser such IE, firefox etc.
( open a command prompt and type netstat -an )
It seems that you have to open some ports on firewall or router that are used for some applications take an example msn or icq. Or you wish to route internet request data to your internal network such as web server.
But you do not have stated anything but just the open TCP port. It's hardly to give any correct solutions for you.
Please includes what you want to archived and what need to do. That will help solve your issues faster.
